CMS Made Simple Forums

In the module help, it says that Front End Users can handle hundreds of users.  What about thousands?  I have a client who has in the 2500 to 3000 range for clients and would have to grant each client access to a password protected page.  Would i be better served by building a custom users database outside of cmsms and linking to it?

thanks for any input!

No you can use it for that many users...
