In implementing this, I had the following issues:

(1) There was no UI to filter out certain accounts from those being 
followed. (Trust me, I have my reasons.) So I used the following in 
input.php, just after the foreach $tweets as $tweet,

if ((strtolower($tweet->screen_name) != ("shoalsbiz")) && (strtolower
($tweet->screen_name) != ("shoalsarea"))) {

and closing the if statement just above the $i++


(2) The url created by the hashtag "tagify" fuction (in 
class.twitster.php) resulted in no a query that returned no tweets. I 
decided I wasn't interested in this functionality, so I just commented out 
everything inside the function.


(3) The RSS page seems to have a number of issues. First, it didn't filter 
by my hashtag. My solution to this was to insert the following into 
RSS.php below the $options = array();
$tag = $_REQUEST['tag'];
if (!isset($tag) && HASHTAG) { $tag = HASHTAG; }
$options['tag']    = $tag;

(4) Also on the RSS.php, strangely, the hashtag was replaced by a space. 
Setting $cleantext = $tweet->message; (the same as on the index.php page) 
fixed this issue.

I hope my feedback is helpful to others and to the developers. I'm sure my 
fixes have issues (probably with pagination), so I hope others can take 
them and improve. Thanks.
