Also, feel free to check out hoodie time (http://hoodie-time.livejournal.com/), if you haven't already. It's chock full of fics like this, and it has a gen tag.

Yes thanks, I use 'Hoodie Time" all the time

It's just the Tags get so mixed up (in my mind) and the Gen Tag at the begging of the page are a hit and a miss.

Can you search more than one tag at a time (that would save me so much time)

You can! Simply add the tags like so:

http://hoodie-time.livejournal.com/tag/tag1,tag2?mode=and

or

http://hoodie-time.livejournal.com/tag/tag1,tag2,tag3?mode=and

It does save a lot of time, doesn't it? :)

Hi it's me "SweetiePie_SPN why is their a goat from the links?

Because the tags in the links aren't real. That's just to show you the format you need to use.
