Bookmark Function

As the title, I think a bookmark system is good on arcade which you can check or uncheck bookmark of other people's game and system will inform you messages if one of the following condition is happened:

01. He/she uploaded a new version of his/her game.

02. Have any new comments on his/her game.

That's it. What do you think? =)

It could be an interesting feature indeed.

Something like a "Watch" button on dA.. The site's alert system could benefit from updates from the arcade :)
