reminder hack??

[butty]

just thought of an idea for a hack, dont know how easy it would be able to do or anythink coz im a php cripple.

n e ways, could do with a button on each post that when ya click it it takes ya 2 a screen where ya put someones member name in n it gives them a icon next to it or summet like that.

so basically if i read a post and think oh joe bloggs would find that interestin, hit the "tell another member" button and put his name in and hel get sum sort of indicator nest to the post so he knows the post sum 1 feels will be of relevance 2 him.

watcha think, can this be done??
