Ok, so here it's a quick guide. You need a hosting with PHP and cron to use is. It's quite different from tweetlater because it posts random tweets from the tweet table.
Step 1:
Put your twitter username and password into the following part of the script:
$username = 'username';
$password = 'password';
For each twitter account you'll need a separate file.
Step 2:
Enter your tweets into the following part of the script:
$input = array ("tweet1", "tweet2", "tweet3");
for instance it should look like this:
$input = array ("going to the gym", "reading BHW forum", "having kinky fun with my gf", "listening to MJ songs");
You can add a lot of these messages. I use about 500-700 for every account and I schedule them to post every 2-3 hours.
Step 3:
Save the file as twitter1.php (or anything you want) and upload the .php file to your web hosting account so you'll get
http://yoursite.com/twitter1.php. Now put your browser to it. You should see a simple message - "success". Now take a look at you twitter timeline - a new random message is posted. And the best part - the footer of this message shows "from the web" instead of "tweetlater" or whatever.
Step 4:
Automate the process: set up a cron job on your hosting account to run
http://yoursite.com/twitter1.php every 2 or 3 hours. You can do it through cPanel - read your hosting provider wiki/faq how to do it.
That's all. It's simple but effective. The hardest part is to get a list of messages. Here's how I did this in... MS Excel
1. write a list of 10-15 verb-like phrases such as "thinking of", "writing article related to", "browsing the net for" and put in the first column of an excel sheet.
2. get a list of noun-like keywords related to your niche from g00gle keyword tool and put it in second column, something like this: "weight loss", "acai berry diet" etc.
3. join these two colums using excel's funcion. you'll get results in the third column: "thinking of weight loss", "browsing the net for acai berry diet" etc. <- these are perfect tweets!
4. add results from third column to the script $input = array ( ...) You can try to use Notepad++ for this. Remember that your tweets must be in the following format: "message1", "message2".
I hope this is helpful.
