Hello Sylvanboat-
Next time you sign in, look to see if there is a box to check that says something like "stay signed in"... (it's been a while since I have had to actually sign in because I checked my box to stay signed in)... but as with most forums, you do have to be signed in to post.
I hope you get this cured with relative ease because this forum is worth being part of... so many good threads and great advice!
