In my personal opinion, the welcoming message could use a tune-up in its design. As of now, we've got this:
This is a modified server created by DougJustDoug for the purpose of play-testing new pokemon created in the Smogon Create-A-Pokemon project. To load the new pokemon sprites, and for general information about this project, visit:

Please use English in the main chat area.
Have fun!
This is probably a bit too long and bulky for the average newcomer to immediately look through. So, maybe put this at the top, instead:
If this is your first time on our modded server, please visit here for relevant information:

It gets most of the the needed information out a bit faster, at any rate.
If it's really needed we could try to abridge the first paragraph a bit:
Modified server created by DougJustDoug to playtest Pokemon created in Smogon Create-A-Pokemon project.
And even though it's somewhat redundant, especially when paired with the rest of the rules:
English only in Mainchat. Have fun!
The "Have fun!" was added in because it's very decorative.
So, the abridged message ends up becoming:
If this is your first time at this modded server, please visit here for relevant information:

I dunno, it may help, or it may not. But streamlining things to make it readable for the short attention span couldn't altogether hurt.
