When you sign up for StrategyWiki, you need to pick an account name. The possibilities are near-endless, but there are a few names that aren't acceptable, either because the MediaWiki software which StrategyWiki runs on won't allow them or because the names are demeaning/likely names for vandals.
Forbidden Characters
These characters are forbidden in names, as the MediaWiki software will either not allow them outright, or editors will have issues talking to you on your talk page because of what the characters are. The ASCII character codes 0-31 and 127 are disallowed, as are the following characters:
# < > [ ] | { } ? % / +
Numbers
Do not create an account entirely of a long (over six characters) string of numbers (like 850013298 or 0155007), as such accounts will be suspected as being spambots or vandals, and that kind of first impression is not good. Try to shy away from random sequences of letters as well. Even if you aren't a spambot or vandal, having a long, random sequence of numbers or letters makes it harder for people to remember your name.
Derogatory Names
Do not create accounts with words that can be offensive to other people (like racial slurs and curse words). Also, do not create accounts that specifically bash another person or people in the name (like "<insert name here> is gay").
What Happens?
If you decide to break any of the above guidelines to picking out a name, it will be immediately and infinitely blocked from editing. If you think that your name is appropriate, please create another account and appeal to the sysop that blocked you or to the community so that you may be unblocked.
