I think in MainForm you should add your event hadler in this way:

frm.OnUserRequest += new UserRequest(frmMain.UserReq);

или если .NET2.0 или старше просто += frmMain.UserReq.

Но проблема тут в дизайне и не совсем ясно, как будешь потом отписываться от евента, ведь дочерняя форма-то уже может быть диспознутой. Так можно и мемори ликов нахвататься.

Но ИМХО есть технологии которые избавят от написания такого кода. Smart Client Software Factory (CAB) и подобные...
