I've had an issue for a while now that has been bugging me. Sometimes I like to set up a follow with deliberately vague parameters. For example I won't put in a subbers group just to see who comes out with the title I'm interested in. Or I'll setup a title with a BD requirement because I don't want to miss the BD version.
Often (possibly all the time) when the desired title is released the item shows up in the new follows list and stays there. To collect it I must click send to RSS. If I do not do that then no amount of "fetch feed" and .* regex patterns will be able to find the title from Deluge.
For the record I am using Deluge version 1.3.12 with the YaRSS plugin version 1.4.3.
For completeness sake; when the title does show up my approach is to edit the follow, add the additional parameters I wish to include (such as the subber group who got there first or whatever) and then save the follow making sure to set it to include all matched titles, as opposed to only new ones.
