"What a joy to come here and read C.I.s"
and so true! LadyM, what I can't wait for is reading your C.I.s!
We have not yet heard from anyone else having the same problem LadyM is having (which I would describe as losing the normal-looking page when you log in from "guest" to "member"), which keeps her from joining in.
Mystery, can't tell you what a Great relief to see that you can both get here and sign in to post. All the advice I have for frequent requests to reidentify yourself is to check off "Remember Me" when signing in. Ramblin' does that and still has a problem for some reason. DeeClutter used to discuss this happening to her, but I don't remember whether this was particularly after a change to the boards. She would advise about composing, then copying, then trying to post, and if there was another ID request we'd have our saved post at our fingertips.
