Would appreciate some help.

This has been going on for months and I can't figure out why????????

I sign on to the site with no problems. It recognize's me as mrhvacmechanic and I'm logged on.

I go to my last post (which always don't appear until the next day??) I click on it to read the replies and I'm sent to the log on screen asking my name and pass word????

Please help???????????????????????
