This is a plea for help from a very confused RhubarbCommando, whose leaves are gradually turning brown and whose stalk is withering (!)

I have recently acquired a bran new machine, which has been set up in my castle, in the turret room just above and to the left of the portcullis. The machine is connected to the telephonic system so thoughtfully invented by that nice Mr Bell. I can view AWAD, inter alia, and continue to derive much enjoyment from it.

Aye, but here's the rub. I cannot achieve a two-way communication with the board. Every time that I try to log in, using my accustomed password, the board refuses me entrance. How do other users who post from both home and work manage it?
Am I going to have to employ my immense vegetative skills as a Commando in order to force an entry? Perhaps, as in Bridge, I should try to force an entry with a spade? Maybe I should use my spades to form a bridge? As it is, I'm forked if I know what to do.

I have perfect confidence, however, that someone out there among my friends will know the answer.

with sorrow, your drooping, sugarless and custardless Rhub.
