Hi,

Not sure, but you posted, therefor you are signed in to both My Grid and the forums [same account].

Occasionally, when accessing My Grid > My Profile you are required to reenter credentials, just to confirm you are you and not someone else walking by your computer and messing with your account information.

If you're signed in, then left over the post there are 5 buttons to take various action on your posts, to include editing and deleting. Editing is time limited... not that you can come back in 6 months time and change content.
