Just remember folks, if you're determined to get HSTB WU's and thus, reach your goal - you can, just by following the simple suggestions outlined earlier in this thread.

Basically;
don't have the "If my computer can process work on my graphics card, then please send me work to run on my graphics card for the projects that I have selected above." option selected,
Only have 'Help Stop TB' selected as your sole project,
Set a decent cache (say, 1.5-2 days at least), so your computers have a chance to build up a stock of WU's, and
Set up either a cron job or Windows task scheduler job to submit a request for new WU's at nn:03 and nn:33 hrs.

There's not a huge amount of HST WU's available - but there's enough for people to slowly reach their goals.

If you are concerned about running out of WU's, when your cache gets down to ~0.5 days, fill it up with another project, then return to 'sole HST' mode again.

Once you've achieved your goal, then you can be mightly proud of that fact - as this is 'one of the trickier' projects to achieve goals with.

I have been baby sitting HSTB for a while and am now 11 days from my next badge. Lately, I have not been getting very many tasks using the :03 and :33 times. Has anything changed in the last 3 or 4 days? It looks like the same number of tasks have been sent out(4000+). Have the delivery times changed? Anyone else notice a change?

Four days later, I still can't pick up any HSTB tasks even with babysitting. I see that the daily feed has decreased so maybe that is the problem? For anyone getting any of these, what are the times that you get them? Still at xx:03 and xx:33?

I have 12 Smash Childhood Cancer work units ready to start.
One FightAids@Home-Phase two running.

It seems that whatever was holding up the tasks has been resolved. Things are back to normal for me and now I have several in queue. I can usually keep a supply but this was the longest period of time when I got absolutely nothing. A few more days and I will hit my 2 year sapphire and then I will concentrate on FAH2, SCC and MIP. Only 35 days more to go and on my little machine, maybe 9 calendar days.

Today I got 6 Work Units.. They are the Large T325 ones 13+ hrs on my I5 @2.7ghz
