If you aren't in the twitter "roll" on the front page then this isn't for you! (If you want to be on it – contact us…)
Otherwise, if you have an occasional tweet that you do not want to show up on the redgloo frontpage, then use #noRG (case in-sensitive so e.g. #norg works as well) tag in your post and it won't show up.
In case you wonder why #noRG – it stands for "no RedGloo".
Thanks _Andrew_Harvey_ et Al for this nifty idea!
