If you can’t justify $15/month per Hootsuite team member, you should check out GroupTweet.com. We obviously don’t offer all the features of Hootsuite, but GroupTweet will enable an unlimited number of team members to contribute content to a single Twitter timeline for only $5/month. You will likely need to sign up for the premium account because you won’t want all of your followers to be able to publish DM’s to your Twitter timeline. The Premium account will give you features such as Author Whitelisting or Message Moderation. With a GroupTweet enabled account and Author Whitelisting enabled, you can have an unlimited number of team members contributing content to the main Twitter account. Your account will also be protected so that only the team members that you specify can contribute content. You can also tinker with the Broadcast template so you can display each contributors twitter name or just include the message without each team members twitter handle, so that your followers would not be able to see a difference between one team members contribution and another’s. One of the advantages to GroupTweet is that team members can use any Twitter client they want to publish to the main Twitter account. Use Twitter.com, sms, TweetDeck, Seesmic, Hootsuite, whatever each team member is most comfortable with. No need to download a specific client or for each team member to use the same client.
