If you have a very slow room I would suggest you make the best of the time but updating photos and anything else. I am just a member but I would recommend you have at least two galleries on your public profile. 1 with pics of you in all your outfits and costumes. The other pics of any and all toys you like to use. This way a guy looking at your profile knows what you have for clothes or toys and might see something he likes and then tips for it. And if you are on cam when updating photos of outfits that might even help draw people to your room. Maybe put in topic "Fashion Show Photo Shoot day" or something. But even if few show up, you have at least updated your profile.
Another thing you could consider, if you have had some regular visitors, is to just send them a simple note via MFC Mail that you are thinking of them and miss them. When I login to MFC I'll often get one or two INSTANT PM's from girls I've visited. Even if some I really like, PM's to me are more intrusive. Especially when it's just "Hey" or "HRU?"... BUT, I would be much more responsive to a non intrusive little note that arrived via MFC mail.
Just my suggestion for something to do when you are on cam and it's really slow.
