add the ability to direct message privately between characters

Since the achievements have a timestamp on them, could you not include them among our tweets and / or the rss-feeds. That way you could see a timeline of sorts on the character.
More things could be added I guess, as level, repgain or skillups.

My server is Frostmane and I have to click through an awful lot of pages to get to it in the list. Moving two pages forward is not a very large jump, but 50 ahead is too extreme.

Add ability to block tweets from specific users

Currently twitter has the ability to search for posts people have made, it would be handy to have that with this as well

I use TwitterFox for Foxfire browser and would love something similar for WoWTwitter.

I would love to be able to upload my own avatar of each of my toons rather then the default wow icons.

Or at the least allow us up upload a 'bio' image on our toons profile page, something maybe 200x200 max that would sit where the small avatar image is...

...or allow both! our own avatar plus a profile image!

It would be nice to not have to stand there and refresh any page time and time again. A self refresh every 30 seconds to every 2 minutes would be very nice. That way you don't have to keep refreshing it yourself. It is also confusing when you are new to twitter and trying to get new twitters to show up that you have to figure out that you need to refresh it yourself.

I believe we need something to put a plug on Goldsellers before they even start. A block function starting at the first reported post, that stops them from posting again after a number of reports are sent in. Blocking that account tied to the reports from posting anything further and removing their posts from being accessed until investigated.

an easy way to post an amorylink for a charakter instead of using 100 charakters in the update-box

so you can make the tweets available to select groups, or just yourself.

Without one I'd never sign in to see these and therefore have no specific use

Besides being thru google allows its to penetrate my work internet firewall :)

There should be a How-To Guide for anyone who has just started using wowTwitter. It can get very confusing on how to use different channels, follow someone, mark something as favorite, respond to someone in the "Everyone" channel, and many more.
