You are very welcome.
You'll find that there's a lot of collected wisdom already available. Either you can search the forum for keywords (e.g., "museums", "restaurants") or check out the Before You Go and Things To Do sections (you will see links to those in the left side bar under More on Budapest). These are all Wiki articles, authored and edited by forum regulars & vacationers who come back and want to record good tips for posterity.
In my experience, you'll get the best information from our forum by asking specific questions like "If I had to choose only one, should I go to the Terror House or Communist Statue Park?" and especially if you give background on your own likes and travel style, e.g., "I like to rough it and eat like the locals, can you recommend a 'dive' that has cheap beer and home cooked food?" or "I prefer luxury and top-notch service, which are the best restaurants for me?"
