Is there a way to mark a forum entry to a favorites list so I can easily find it again later?
Yes, if you right click on the title above each person's post (in this case "Forum Favorites?") you can get the link location or save the bookmark directly to your browser etc.
if you mean a favourite list within GLB.com, err...
Yeah, I was meaning within the forums since I access it from different computers. No big deal though. I can just use delicious.com I guess.
On other forums it's common to do a reply to the post you want to find later and then use the list of last posted on your profile. This however clutters up the forum with unneeded posts so is in general frowned upon :)
I use Opera with opera Link. Works great on all my devices, syncs the bookmarks and start-page in the background.
For sync all I have Xmarks, it's free plugin for all Browsers, explorer, opera , firefox etc...
Yo can sync something like historial, keys and more.
