If your web browser has a search pane above, and supports the opensearch standard, you should see it glow in one way or another. Clicking on the glowing area should offer you the chance to add one of two search functions that you can use to search Freeola Chat. One via Hmmm...'s search page, dubbed Hmmmola and the other directly via Google, dubbed Freeoogle.
Whichever you choose is up to you (you can choose both) as the search results will be the same (as it's all done by Google), the only difference is with Hmmmola, you can select individual fourms.
