thats the thing la, sometimes people have to stop expecting to be spoonfed and learn the more "advance" tricks. besides, its pretty simple, in fact, i'll include a mini tutorial here.

Stage 1: Enabling the Console
1. At the main menu, click on Options.
2. Next, select the Keyboard/Mouse tab.
3. Check the Enable Developer Console checkbox.

At this point, you can press the tilde key (the key on the left of the number 1 on a full sized desktop keyboard, which looks like ` or ~) to open the console.

You can then type in "openserverbrowser" (without the quotes) which will do exactly that, and browse for the E-club servers.

Stage 2: Setting the search key
Assuming E-club (or your own server if you have one) has set the sv_search_key,
1. You type in "sv_search_key <yourUniqueKeyHere>".
2. Create a lobby like normal and invite your friends.
3. Start the game. It will automatically search for a server with a matching search key. Presto!

Not that difficult if you ask me. the benefits of this are that you can use the lobby instead of the server browser, which means you can select the game mode, and your character, and also the difficulty.
