1. Pop-ups are not going away, rslitman. Do you know how many articles I link on here that give me pop-ups when I go to their site? We have one a day. If I got direct to messages or moderator control panel I don't get the pop up at all. I'm sorry you feel personally offended by a single pop-up on a free site.
2. I have not gotten any more spam than I normally get, certainly not railroad-related. I use a Yahoo! address for my registration here. If you're getting spammed, it's likely from something else you signed up for. This reminds me of a time I sent out a blast email, not long after the new owner took over, to our members. I got one back from some Doctor (you would have thought it would be a l (itawyer) telling me how dare I "spam" him. It was a message from the owner; is that spam? Not really. He demanded to know how I got his email address. I looked up his profile; he had posted a query on here. I sent him the link to it. Never heard from him again.
3. That said, it's not my place to recommend how people should register for the site. FWIW I have dedicated emails for several different purposes. Patrick's recommendation is good.
4. Approach, you may have a spambot on your computer. Most AV softwares come with a spambot tool. I suggest if you haven't run it recently you do so. I run mine a few times a week. If you notice the spam comes piggybacked onto a topic notification, it may be looking for that. Or it may be a coincidence; I don't know what type of spam you're getting.
5. I still clean out almost 500 spam registrations a day. It's a huge pain. If you ever get a message from a user you don't recognize, don't open it, don't email, etc. Spammers should not survive past their first post or registration (I prune daily for zero posts).
Next stop, Willoughby
