Thread: creating a blog with very basic C# understanding

i have a very basic C# understanding but i want to create my own blog for my own website...
here my code so far:
i have problems by calculatings the 3 labels, tuit from the current person, followed people from the current person and total of tuits together with all people.
The other problem, if i log for exemple tom 1 own tuit or Anna two own tuits have to be displayed by login and if they follow someone those tuits has to be also shown but not all tuits from the tuitterMessages.txt...
How can i handel this? need some example please...
another point when i follow one potential user the code is good if i want to follow a second one i have an error, what is wrong? then user also appear 3 time each after i follow the first one.
If i want to remove the person i follow i can not the page blocked...
