Okay, seeing as how this site has a donate now block, I'm sure one is already written. I cannot find it though... I generated my button at paypal, but I'm clueless on creating a blank block to hold it.
Thanks,

Try xDonations here.

Or to create a custom block with your HTML code, go to System Admin > Blocks & scroll to the bottom of the screen; paste your HTML code in the big box, write the title of the block in the little box, select Visible > Yes & choose the pages you want the block displayed on.
Then, at the very bottom you will see a drop down selection box with "Auto Format", "HTML", or "PHP" - choose HTML. Then hit return.

Then go to System Admin > Groups and enable permissions for guests, if you wish Guests to view the block.

Hope this helps ;)

Thanks! Awesome responce time around here, I can't imagine using any other product :)

how do I change the text of the paypal block, as well as tur off the quota/goal aspect of the block?

thanks
