The way I do it:
* Add the addons I use to my
favorites list (this gives the authors a feeling of being loved - Minion doesn't do this
)
* Whenever an addon is updated, I get an e-mail notification
* I go to my favorites page or open the link in the email and download the zip to the AddOns directory.
* Delete the old addon directory and unzip the new version.
* /reloadui
You could use Minion of course, but I prefer to control when to update things..
