I'd guess a lot of people who actually read the forum probably don't need to be told this, but please take care when adding new artist names that have '@' in them. Frequently the text after the '@' is just some sort of status text. Cases in point:
* fob_@_tsu_it_ta (somebody just got a twitter account!) - Pixiv artist name is currently ふぉぶ@春東ミ33ab (somebody's going to some event I don't recognize!), a better artist name would probably be fob_(bluuue) (from pixiv filename) - but, in fact, we actually have a bluuue that's the same person! (The name@event_location pattern is pretty common, and I remember changing one such post recently.)
* minu@maipiku_boshuu_chuu (now taking applications for MyPix! - there's at least one other artist like this) - current Pixiv artist name is just みぬ, artist name at website is みぬき, so minuki or minuki_(hidamaranai_hibi) would probably be best
* kurukuru@fundoshi - current Pixiv artist name is クルクル＠, twitter account is @ql_ql (name is クルクル＠謎の人). kurukuru might be enough. Of course, there are a number of other Pixiv users whose artist names end in @, so maybe kurukuru@, but aesthetically that's...
* juuka@100neko - is still this person's Pixiv artist name, but actually that should be tooka according to their webpage's domain name (tooka-ansoku).
It might be worth adding a note about this somewhere people might be more likely to see it when uploading or tagging. There aren't too many artist tags that have @ in them, so I'll go try to look at them all this week. Most of them are pretty small, so I don't mind retagging those cases, but I may come ask for a few tag moves. (I guess once I'm done with that I ought to go look at some of the pixiv######-qualified artists...)
