my problems please reply fast!

Hi coleagues, i'm also programmer, so the problems are:

What i nead to sett as smtp server, because i've set smtp.gmail.com and it dont want to work.
Also i'm using 1.3.5 version of pun bb with hotfixes and 8 official extensions and it's really grate, but there are some mistakes,

• forum description can't be set

• also there are always tipos you written most of texts combining capital and lowercase letters without spaces.
  e.g.:
  correct: I'm a programmer
  you written: I'mAProgrammer

• i'd really want to see one extension that allows invite, but which will not disallow to user join without invite

• please, add stop bots captcha while sending email message via the forum!
