Do you want just titles for your missions or do you want to find some combined op missions?
To find them, just browse through the OFPEC mission database.
For titles and stories though, the OFP Story Depot will be up soon. ::)http://ofp.gamezone.cz/_hosted/stories/index.htm
That's where it is but it isn't finished yet. Don't worry though, Homefry, Seal84, and me are gonna start this up soon.
