Good to be back on a Martin forum!
Really don't know where the "old" forum went but, glad to have found this one. Been "martining" for 12 years or so up here in Delavan, Wi. Had a hawk hit 5 years ago. Birds left. Next year put my house up with a home made hawk protector up and got most of them back. Following year installed the protector and got the birds back again. However, the next year I believe an owl hit and they left once again and didn't return last summer with the guard installed. So this year I put up the house without the guard so we'll see what happens. Strange happenings!!
Hi welcome back, I think this is the old forum with the new facelift you have to get used to it ,I think you'll like it better. It's still has a few glitches but on the average it has some real nice new things also. Actually, I think it's still the best one of course some people say I am A little biased ,like my wife , but she's not always right 
I hope you get your difficulties straightened out and your birds come back. Ed.
