Odd. You must be typing something wrong in the e-mail address or, if you're using EN World's e-mail sending thingamabob, you must be missing some check-box or button or other. I've gotten several e-mails through EN World before so I know my e-mail address here is correct. I do not use instant messengers.
It would be easiest if you logged in, clicked on the Quick Links dropdown button, then Edited Your Options, and selected the checkbox to allow e-mails from EN Worlders. AFAIK you need an e-mail address to get an EN World account, so your e-mail address should already be in the system. It just isn't accessable to anyone (except
possibly Moderators). AFAIK the system won't display the e-mail address for other people when that option to receive e-mails is checked, it just allows us to send an e-mail to you without knowing your e-mail address. You could uncheck the box after receiving an e-mail from me through EN World.
It's an option, anyway. I'm leery of posting my e-mail address openly, since that's how spambots find it. If you had dropped by during the game on Monday, it would be a lot easier, since whispered messages over OpenRPG aren't accessable to anyone else (I know, I've run my own server for games before to try avoiding lag, though my computer no longer works well enough to handle that extra load).
However, another player dropped by this Monday during the game, someone Dragonwriter/Dragonson/Fahlias, one of our other players, recruited. This new player worked up a Halfling Rogue 13 while the rest of us ran the session as normal, and his PC will be joining in at the next session. Combined with Scion/ScionJustice's bard/sorcerer/Gnome Dreamwalker, that brings our number of PCs up to 6. Fahlias, Szitha, Fleck, Ak'man Utan, Seebo, and the halfling whose name I just forgot. Plus Argus, the NPC/DMPC, my sometimes-PC and sometimes-NPC (since I'm not usually the DM).
One more PC is alright by me, but since there'll now be a halfling rogue in the party, there's a distinct lack of any need for a trap-monkey, since that rogue will be filling the position.

So you'd need to come up with something different, or just not so focused on the trap-monkey aspect (obviously I can't be sure yet if this new player will show up consistently or not, so it's still possible that after a few weeks we might once again have no trap-monkey).
