people seem to think, that because they are awake, then the rest of the world should be awake to deal with "their life crisis"
sorry to tell you thin, but you buy something from a seller, they are not a store owner just around the corner from you, but they could be on the other side of the planet, 12 hours time difference from you.
while you are working other are sleeping.
because this is a global community its so easy to forget that 1/2 the planet is sleeping while the other half is see more awake.

A few more issues people forget,
#1 religion,
some do not allow its members to work on some days of the week.
others force times of praying to their god,
so not everyone can jump when you say jump.

#2 national holidays,
not everyone follows the USA in its holidays, some nations have holidays that others do not.

#3 Family
the seller is a human, the script aint, the seller might have family issues, a sick child, dying partner, or other crisis that takes them away for more than just a day or two.

#4 paypal addresses
people are wise to use an email address that they do not use for regular email for their paypal payments. so most smart people don't read any mail sent to that address because they do not normally use it for mail. so you are not being ignored, its just that someone is not reading the mail because they do not use that address for anything but paypal.

Boonex:
the staff here work hard, but the seller is the one that sets up their store and payment setting. not boonex, so if some set it up wrong, you get some sales going wrong.

boonex has some issues and they are being addressed, they have almost dropped everything to work on the issues that have been brought to their attention by members and myself, and thats putting things behind a little.

Dolphin is a huge project and it is not that easy to learn by someone new to it. but over time you do learn,

my best advice to you is this.
Dolphin will work great if you have all the server control you need. A dedicated server is best, a VPS will do but i wonder about the disk space on some of them.

shared hosting? use the one boonex recomends, dont use godaddy and a lot of others.

the most important thing to remember, do not buy or use free mods if they are not for the version and build of your dolphin script, unless you know the person you got it from, will help install/fix it as you upgrade your dolphin install in the future.

because they are what goes wrong with the upgrades more than anything.
