Thank you justin. That is perfect and thats what I was after.

Just 1 last question, is it okay when I add multiple cron jobs like the above (1 for easysocial, 1 for komento, etc...) with different timings for each command inside the same crontab file itself? Will that work?

You can simply add additional lines while you're in the crontab editing window. I myself use the following along site the one above for ED and EB:

*/5 * * * * wget "http://site.com/index.php?option= com_easyblog&task=cron&tmpl=component" >/dev/null 2>&1

*/5 * * * * wget "http://site.com/index.php?option= com_easydiscuss&task=cron&tmpl=component" >/dev/null 2>&1

You can adjust the times for your crons as needed.

Awesome...

I was wondering, with the user activation emails, does that go on the cron job queue as well? I am thinking of maybe having the cron job interval as 10 or 15 mins but I dont want the users who are waiting for their activation email after registration to be waiting for 10 mins or more just to receive that email. So are user activation emails sent directly or does it go on this cron job queue as well?

I believe those are sent immediately after registration or approval from an admin. You could always do a few test registrations to see if that's the case.

When a user registers on the site, it doesn't make sense to add these notifications in the mail queue because the email should be instantly sent to the user Having them wait for an email is not ideal

Perfect. I can then safely increase the cron interval to 15 mins without worrying. Thank you Justin and Mark.

You are most welcome
