how to share user preferences between projects with multiproject trac?

I've a multiproject trac setup that works perfectly for any single project, intertr开发者_StackOverflow中文版ac links are fine too. My only problem is that my users have to provide their preferences for every project. Is there an easy way to get around this and have user preferences shared among projects?

thanks, Viktor

You should take a look at the TracUserSyncPlugin that promise just that. Currently it's marked "beta" and "unfinished", so you may want to join in for more development, but at least you'll have a starting point.

There's not an easy way to do this that I know of. However, user preference data is stored in the database so it should be possible to write a script that synchronizes the preference data between the different databases.
