How to Automate Anything
Step 1: get imacros SCRIPTING edition and a macro program like macro express or AutoMate
step 2: learn the basics of imacros and automate6 its generally simple and explains itself and both programs have a large help file and site.
step 3: once you got the basics down you can dive into the key part to the operation, visual basic scripting(VBS) now VBS can be used alongside imacros and provides a TON more functionality for imacros, heres an example of one VBS http://wiki.imacros.net/Random-Numbers.vbs. Here is a small adaption on how you might want to use it with a snipet of the code from the random numbers vbs code
rn = cint (rnd()*5 + 1)
select case rn
firstname = "mark"
firstname = "jack"
firstname = "steven"
firstname = "luke"
firstname = "mike"
firstname = "erik"
'Set the variables for imacros
iret = iim1.iimSet("-var_firstname", firstname)
So basically when a VBS runs it generates variables for imacros and in this case randomly picks one of the names and then sends it to imacros which uses those variables where you need them. typically people have it choose one of 9000+ first names and 15000+ last names along with several random letters and numbers for inputs and such on signup so EVERY signup is unique.
step 4 - Captchas
now this is the part that plaques most people. How to get past the captchas. Well you can use our captcha service which starts at 8 dollars for 1000 captchas which = .008 a captcha down to 300 for 50000 which =.006 a captcha. Its directly made for imacros and you basically just plugin a couple lines of the code on the site and you never have to worry about captchas again.
STEP 5 -extra stuff
another key thing is making an error macro for when things go wrong or you get the captcha wrong. You input what macro to run in your VBS script and when the error hits it will run the error macro you choose. Basically what i do is cut out all the stuff leading up to the captcha and just have from the captcha on being the error macro and this works perfectly.
