I wonder what is the current solution to this particular case. Some people just want to pay subscription fees for more than a year, others, including me, discovered that they require more storage space at some point and did the upgrade instantly, thanks to Zotero for this excellent option, but then the expiration date fell on a close date when I may not have a valid visa card, leaving an undesired gap of not being able to pay online for the renewal. I would rather pay now as long as the credit card is valid. I emailed storage@zotero.org but no reply yet. If I do not get an answer soon, I must consider shifting storage to Webdv. I have good storage on Dropbox, but I wonder if someone got Zotero Webdv to work with Dropbox. The last time I tried it on a Linux machine, it didn't work, if I still remember.
@dstillman, thank you for your quick response. You are right. Sorry, my bad. I just discovered that I sent the email to myself and forgot to include storage@zotero.org!
@dstillman I sent the email to storage@zotero.org. Could you please care to reply? My card will expire by the end of this month. I truly appreciate your timely response.
I just sent the email now.
Best regards.
