HOW DO Y'ALL DO IT?

How do you keep them all upgraded?

Paitence, organzation, teamwork, help, and by planning ahead always.

I do the same as Kyuubi hah! I pay for my accts with RLD and have a LOT that usually expire around Cyber Monday each year xD ...and I take advantage of any newletter/other coupons and reupgrade anything that is the closest to expiring then. :P

Selling tickets and shows/show spots. 

I pay for my own upgrades with RLD for now. But I only have 10. When my project starts ill be going to at least 20...*probably* more.

i dont remember the last time i paid for an upgrade. 
I have 25 and just use a notepad doc
I save all money from spots/tickets and use that.

I try to upgrade a month before they expire

I have mine strategically split so I have around the same number expiring every month. I take advantage of sales and coupon codes. Trade my tix for upgrades. 

I'm just returning but I only use RLD when I have to, and usually only pay for one month upgrades.  (If I pay for a six month it's usually to auction for show funds)

I keep a master google sheet with all my show and ticket info so I can keep that stuff straight, and then use that money to keep everything upgraded and add more upgrades.

On a google doc I have a list of expiration dates from the soonest to the latest, and I am constantly upgrading those in order as i am able. When they are all at least upgraded 3/4 months out I will add new accounts upgraded with HPD.

And continue on like that if that makes sense lol.

I am lucky to be able to afford RLD.
Before, I used show/graphics income though.

Lumos made me a master google sheet a long time ago, and I'm forever greatful for that.  With the help of Moorf it stays pretty updated as best as I can get it :D  But I'm usually on the struggle bus with keeping up with upgrades xD
