How do I post the same thing on all clubs boards without copying and pasting for the next 2 hours?

I know I am a technophobe but there you go.

You can't. Make sure it's not seen as spamming.

Admin can do site wide announcements that appear at the top of the board. Depending on what you want to communicate you could approach them.

Cheers Iain.

I want to post something about the latest RFL hair brained proposal to restructure kids rugby and gauge opinion on it. Do you think this will get thru?

I doubt it's classed as spam, but some board mods may see it as not to do with their club and something for the general RL forum (the VT). I doubt it would be the sort of thing that would be done as a site wide announcement.
