The off topic forum is for postings that are probably of interest to the community, but not directly related to portable apps. As suggested, topics like asking for CMS suggestions, Windows themes and things like that can be posted here. It's not a free for all for posting anything and everything.
If your post is suggesting a service or product and linking to it, it probably doesn't belong here.
Note: Posts in the Off Topic Forum will not appear in the Recent Posts tracker.
