The best one I am looking at is combining Twitter, FB or any Id's and tags with internal identifiable tags.
For example, $CoralSiteEvaluation$ or $Project:CoralSiteEval$. So this might be (generally short) internal data and tags for my company. Maybe just a cookie id.
What are the available allowed special characters?
Is there a bot/plugin for that?
Can I use that across all platforms?
How is the related or transformed to database triggers?
