I can agree with The Pharmacist's pessimistic ghost, there are two types of newbies here (basically):
- those who care about the rules and they will study it and will try their best not to break them
- the spammers who won't care about the whole thing, despite of it will be put next to the more menu, will flash red and blue or will stay for 30 seconds at login...
For the first type, it will help a bit, for the rest, it won't... ever... but unfortunately they are the majority now, so I'm not sure if it worths the effort to develop this for those few newbies who are not here to spam...
