If you've had trouble posting a NEW message (as opposed to a FOLLOW-UP message), please describe what you've been experiencing. There are new messages coming through all the time but at least I can say that there haven't been any problems doing follow-ups.
Hopefully, posting a FOLLOW-UP to this post will work for you. Please, if all is well, there's no need to follow-up unless you feel you must. Have a nice day!
