I'm creating a public Trello board that I would like others to contribute to. However, when I log into the board as a different user, I don't see any sort of "request access" link. I could tell people to email me to get access to the board, but that's kind of clunky. Is there a better way?

The best would be this feature request: How to let random users add a card to a public Trello board?. Some sort of moderation queue, in other words. But a prominent "request an invitation" link would be acceptable.

I think the simplest way to do this would be to put an email address in the description that would allow them to contact you.

I'm going to also post this to the 'feature request' trello board, as I have encountered it, in the past. https://trello.com/card/users-can-request-an-invite-to-a-board/4d5ea62fd76aa1136000000c/1368

In the lines of the solution by @bryan-larsen, I've created @welcomebot, a Trello bot that automates the process of getting people into a board.

In his own words:

I'm a bot designed to make Trello boards open for anyone to enter.

If you have a board where you want to let anyone enter, to comment and see and all that, just create a card, name it in any way you want (it can be something like "Welcome to this board, please comment here to enter!") and add me to that card.

Every Trello user who leaves a comment in that card will be automatically addded as a "normal" member to the board.

There's a test board where you can see the feature in action.

What I ended up doing was adding a card that said "If you comment on this card or any other card, I will give you public access to this board."

I did this too. Link back to the feature too, so people commenting can vote on it! – mlissner Nov 16 '12 at 18:33
