Caught between making the final selection between 2 computers - very similar but the area of the video memory, video card, and expansion capabilities is where I am difficulty deciding between the 2.

Any suggestions?

I have some nice people that post a welcome message on my page, but when I go to their page and try to post a comment, I can't enter the comment.

Does anyone know why this is?

I don't want to be considered rude. Please let me know.
