In terms of running numbers, the Rental Property Calculator under the Tools tab at the top of your browser (if you are using a laptop or desktop) is a great way to do so.

I tried 2 different browsers, too.I don't even have a place to check all panelists and attendees, or whatnot.   

Opens new browser window every time you click on a new topic.No jump to first unread post.Shows when the thread was started, not when last replied to.Shows who started thread, not who last replied.Why above each subject it lists the forum you are in is beyond me.

@Matt McGillianSorry the calculators are not yet available in the Biggerpockets app.Please use a mobile browser like Safari or Chrome to access the calculators here https://www.biggerpockets.com/calc

Go to a browser and key in something like "lead testing near me" to get you started.

So when I'm on a mobile device, I still go to the site with a browser.

(Admittedly, I'm running an obscure browser called "Chrome" but I also tried it on Safari with the same results.)Next issue: I've spent the last twenty minutes looking for my inbox.

Just key that into a browser.

I want to open (not in web browser) an existing PDF invoice, add a PAID stamp that allows me to enter the date, amount, payment number/type etc.
