Here is what is being said about extensions from Tom-Muck.com
Sort Repeat Region: "Too cool your sort extension - cuts long hand coding and possible debugging out completely.
This is so sweet - in just minutes I have a full sort - UnReal!!!
The FAQ on this extension is GREAT - by reading that before I used the extension I was able to avoid errors!!! I bought your first book long long ago - and it helped me with a jump start on UD back then.
That was UD 1 - I bought your new book today thinking there may be some new stuff in there. After getting this extension - You make me look really good at work!!!!!! I make a living using MX 8 hours a day - 5 days a week...
Thank you Thank you Thank you" - Debra Wylie
Recordset Navigation Suite: "You are the man!!! -- I just purchased and downloaded your Recordset Navigation Suite and had it running on my website in 3 minutes!! I've been looking for this for something like this for quite some time and was about to roll up my sleaves and code it myself (I'm not a programmer.) You've saved me countless hours and have helped me put my project back on track. The $35 was more than worth it. Your Search Extension is next on my list. Thank you very much and please keep up the good work in enabling us non-programmers in developing exceptionally sophisticates sites!" - Pascal Antoine
Recordset Navigation Suite: "Tom Muck has released a new version of his Recordset Navigation Suite. This extension definitely is a must have extension for the UltraDev developer. Have you ever built a site where you did not need links to navigate through a recordset? We didn't!
UDzone has been given the opportunity to test Tom's new suite and it is almost unnecessary to say: It is a 'must have'. Tom is really setting a new standard for extension developers with all his help files, support of 5 (!!!!) server languages, clear interfaces, output preview before applying the extension to the page and many many more features." -- www.dmxzone.com
"Thanks for creating these extremely useful extensions!" - Stuart Starrs
"Just like to say a huge 'Well Done' for this xtension. It's saved me hours of development time. Thanks again." - Dean Price
"Thanks a lot, Tom! It's people like you, ones who actually help people and don't blow them off that make programmers (and computer geeks) like me want to keep coding!" - Peter Filias
Dynamic Search Suite: "You cannot believe how much time that has saved me... Thank you so much.... Its been a long time since I have paid for something that I really wanted and does what it says on the box!!! :-)" - Stuart Stalker
