Remove cron reliance?

Anyone know if I can force a re-index in magento’s add-on that doesn’t go through cron? I’m in shared hosting that doesn’t give me access to cron so can’t use it. I know it’s possible somehow because the first index worked fine, but now I can’t get an updated one to work!

I guess you can just disable indexing queue. Then you can trigger reindex from admin, which will be executed immediately. THis doesn’T work for very large indexes, though.
