Hi Dennis and Snatch,
You can run a forum fine using a host with the FP Extensions installed. I have 3 of them and occasionally use FP for certain things.
HOWEVER, I would highly recommend that when uploading the forum use "normal" FTP and not FP's FTP service. Even though I actually like FP, I would also NOT recommend using it to modify the forum pages or any other ASP pages. If you want to use a WYSIWYG editor, I would recommend Dreamweaver or others for that purpose.
As a side note, even after you FTP the files, you will notice later in your forum directory (looking through your FTP client) certain folders like:
_vti_cnf
Leave these alone as FP and the extensions use them to communicate. You WILL NOT harm your server extensions using a normal FTP client. Most hosts tell you this simply because they don't want you deleting or overwriting files that the extensions use. For the most part just don't delete any of the directories that have the "_" in front of them.
