ATD’s International Conference & Exposition is a huge event with tons of activities going on. Even if you’ve attended in the past, you might have some lingering questions. Last week on Twitter, we asked you to submit your questions using the hashtag #askATD2015. Below we’ve collected the questions and their answers. Please continue to use the #askATD2015 hashtag if you have any questions; we’ll continue to monitor it throughout the event. Also, please check out conference FAQs as your question might already be answered there.

**What’s the dress code?

**Business casual. We strongly recommend comfortable shoes as you’ll be doing a lot of walking, as well as a light jacket as session rooms can run chilly.

**What’s the hashtag?

**The official conference hashtag is #ATD2015. Tweet early; tweet often!

**Is there a conference app?

**Yes! On iPhone and Android devices, download the ATD Events app by searching your app store for “ATD Events”. We also have a web version available for Windows phone and other devices. For more information visit out app page.

**Where can I learn more about ATD Membership?

**Members at ATD 2015 are invited to attend one of the membership orientation sessions held on Monday, 5/18 at 10:00 a.m ET or Wednesday, 5/20 at 12:30 p.m. ET. With numerous additions to your membership over the past year, you may have access to tools and content that you might not know about. Did you know your membership includes a number of e-books that you can download and read at your leisure? What other benefits do you have that you haven’t accessed? Find out the answers to this and more by attending one of the membership orientation sessions while at the conference. You can also bring your membership questions to the Membership Booth located on the Expo floor.

**How to choose between sessions?

**If you’re stuck choosing between two sessions, you might want to see if either one is being recorded. This year 120 conference session will be recorded including keynote speakers, Andrea Jung and Sugata Mitra. Recorded sessions are noted in the program guide with the microphone icon, or in the Schedule Planner or ATD Events app under the Session Services filter. For more information, visit our Session Recordings page.

**Will there be an International Lunch?

**There is not a specific International Lunch scheduled, but there are several International events planned including a special orientation on Sunday morning and an invite-only reception for all International attendees. You can also always check out the Global Village, open during the entire conference, which is one spot for networking with attendees from outside the U.S. For any questions regarding International activities and events, please contact [email protected].

**Is the Networking Night Event an additional fee?

**Networking Night is Tuesday, May 19th from 7:30-11:30. Tickets are an additional fee and can be purchased on site for $100. The event will include rides and attractions such as the new Harry Potter Diagon Alley.
