This does not represent an official statement made by the staff of Glitch City Laboratories. I do not represent GCL in this post.
Its strong points are the numerous Missingno, 'M, and Glitch City articles and info; that's what made the site #1 in the first place, and probably why glitch researchers like to use it as reference. I'd consider its coverage of Ditto Trickable glitches to be superb to average, depending on the Glitch pokemon in question. The size of the page depends on the popularity of the glitch within the TRsRockin forum community and visitor population, which affects the number of visitor submissions and screenshots available for that particular glitch; the Missingno and 'M pages, along with well-known Ditto Trick and Equivalent Trade glitches like PkMn, .4, and 3TrainerPoke, are generally larger. As these pages are built primarily upon visitor content, the information might not be as reliable as it appears, although, from what I can tell, the information is mostly accurate… except for these (somewhat small) flaws: Some of the larger pages (eg. 3TrainerPoke) take one-time random occurances as cold-hard fact (Link Cable Oddities are pretty much random anyway), as well as minor inaccuracies (PkMn lists PkMn n as a "variant" of PkMn - this is in fact a [[glitchdex/redblue/pkmnn|separate glitch]], a Mankey hybrid if anyone must know off the bat - similar to what happens with Char 'M - Just because the names are similar does not make them related in any other way). The article on .4 attributes some effects of "Super Glitch" to the Pokemon; these are mostly due to the attack itself, which may cause undesirable effects even by viewing its name (whether in battle or on the stats screen). Several glitchdex pages are purely data from Melchior 1 (before update; this means no Over Lv100 or HP info) with no added info or screenshots (see Symbols (C7 yellow glitch - "Female/Japanese/Whatever Symbol(s)" was used extensively in Melchior 1), Z4, 7g, and probably others), while others are purely based on Okk's research, which has Base stats as well as Lv.100 stats (including HP), Encounter/Capture Flags, and TM/HM moves (see p T, Japanese Symbols (C1 Red/Blue)) - these are mostly the least-known of the Ditto Trick group and therefore the most lacking in screenshots and submissions from the community. The most popular of the Evolution and Equivalent Trade group (Q, Charizard 'M, and 3TrainerPoke) also have pages. On the flip side, the lesser-known glitches (minor Equivalent Trade such as $ (F0 Red/Blue), "Glitcherino" (FA Red/Blue), 4h (D6 Red/Blue) and their Yellow Evolution counterparts PkMnp (D6 Yellow), C-I (F0 Yellow) and "Male Symbol" (FA Yellow), and Gameshark-only glitch pokemon) get no coverage whatsoever, aside from the odd screenshot (see "PkMn"). This is because the content of the site is driven by visitor content - the reason the 3TrainerPoke and PkMn articles are so large compared to others (like Z4's) is because visitors do more research on the latter and not the former. This is the only reason people come there and post "newly discovered glitch pokemon" that have been sitting on our server for half a year.
This is generally why I prefer to have the site admins do all the work around here at GCL; a small group of dedicated "experts" (however the hell you define an "expert" of pokemon glitches), rather than a wide mass of people who find random Missingno stuff on their games, seems to work better here (110 ARTICLES IN GLITCHDEX *shot*)
It has some things we don't, I'll grant that. For example: Screenshots. We fucking need some screenshots for most of our articles. And those TM moves. Why isn't anyone here researching those? And with rjaguar3's item mutation stuff (which makes him the 3rd person here to reach Distinguished Member status, congrats :) ), Capture/Encounter Flags finally have a real use (well, Capture Flags already have uses - if you captured a certain real Pokemon, the Capture Flag for a glitch might be set, allowing you to bypass the Pokedex and the subsequent Rhydon transformation).
TM moves. Damn. Why don't we have data on those?
