I would like to know where exactly to go to remove inactive members.

At this time, I am working on getting my password for my forum, but once I do; I'd like to know
where to remove the inactive members at this way I do not have to go searching around for hours
trying to remove them.

Thanks.

Administration Panel>>Users and Usergroups>>Users>>Handle Users

You can generate lists of different categories, like members you never visit the forum.
