Waaw! iText is the editor's pick at Windows 7 Download and Download Typhoon! It's almost like we've won an Award!
However: why are these guys using an e-mail address that doesn't exist, and why do I get two mails that are almost identical? Why would I put that button on my site?
I understand why: the ranking of Windows7download.com is #10,640 with 1871 sites linking in. The ranking of downloadtyphoon.com is #63,914 with 463 sites linking in. They're asking me to put that logo on itextpdf.com to increase their ranking, but... what's in it for me apart from a link back? I'm sorry, but I'm not interested.
